Utility for SSL certificate

Postby Adriano » Thu Aug 29, 2019 1:12 pm

If you need a certificate for your ESP32, you have to download it over some tools like openssl.
I created a webpage, so you can download your certificate directly from this webpage.

Just insert the https server (like https://www.esp32.com) and you will get the certificate and some info about it like validity and certificate type! You will get also the code to insert in your ESP.

Check it here:
https://projects.petrucci.ch/esp32/?page=ssl

Note: I don't know why, I am not able to use the child certificate on the ESP. Maybe it is a bug (https://github.com/espressif/arduino-esp32/issues/3155). But if you use the parent certificate, it works, if the purpose allows it. Unfortunately I am not able to get the root certificate as the server will never send it (it is implemented in your OS, so it is not sent).

If you are developing a page with https requests, this is a good tool.
